Disclosed are a calibration method and apparatus for a coherent light module, and a computer-readable storage medium. The method comprises: obtaining a first and second curve relationship respectively representing a relationship between a power-gain monitoring voltage and optical power of a receiver of the coherent optical module and a relationship between a target setting voltage and the optical power of the receiver in the optical power range of the receiver; determining first optical power based on the first and second curve relationship, which is used for dividing the optical power range of the receiver into two ranges; and determining a calibration mode of the coherent light module based on the first optical power, which comprises: calibrating the coherent light module by using the first curve relationship or the second curve relationship when the optical power of the receiver is in a first range or in a second range.

Disclosed are a dual-carrier integrated optical device and a photoelectric module. The optical device comprises: an encapsulation unit, and a ceramic substrate and two independent carrier assemblies arranged in the encapsulation unit. Every carrier assembly comprises a DWDM active chip arranged on the first heat sink, a first heat sink arranged on the independent control element, and an independent control element for adjusting the temperature of the DWDM active chip to adjust an output wavelength of the DWDM active chip. The DWDM active chip and the independent control element are respectively connected to the ceramic substrate. According to the characteristic that the wavelength of the active chip will shift with the temperature, an output laser wavelength of each active chip is independently controlled by means of the independent control element, which achieves higher wavelength stability and can realize optical signal transmission at different rates.
